Integrated Enterprise Modeling Reference Architecture and methodology – Kai Mertins and Roland Jochem

Integrated Enterprise Modeling (IEM) is a methodology that provides a comprehensive framework for capturing, analyzing, and improving various aspects of an enterprise, including its processes, organizational structure, information systems, and more. While IEM itself is a methodology, it can be aligned with or complemented by various enterprise architecture frameworks to create a more robust reference architecture.

IEM Reference Architecture:

The reference architecture in the context of IEM typically includes several layers or aspects:

1. Business Layer:

   • This layer involves the modeling of business processes, organizational structures, and business strategies. It defines how the business operates, its objectives, and the processes required to achieve these objectives.

2. Information Layer:

   • This includes the modeling of information flow, data requirements, and data structures within the enterprise. It focuses on how information is processed, stored, and utilized across business processes.

3. Application Layer:

   • The application layer covers the software applications and systems used to support business processes and information management. This includes both in-house developed applications and commercial off-the-shelf software.

4. Technology Layer:

   • This layer deals with the underlying IT infrastructure – hardware, networks, databases, etc., that support the application layer. It addresses the technological foundation of the enterprise.

5. Integration Layer:

   • This layer focuses on how different parts of the enterprise are integrated to function cohesively. It includes the integration of processes, data, applications, and technology.

IEM Methodology:

The IEM methodology involves several key steps:

1. Modeling of Current State (As-Is):

   • The first step is to model the current state of the enterprise, capturing existing processes, organizational structures, information systems, and technology infrastructure.

2. Analysis and Identification of Improvements:

   • Once the current state is understood, the next step is to analyze these models to identify inefficiencies, bottlenecks, redundancies, or other areas for improvement.

3. Designing the Future State (To-Be):

   • Based on the analysis, a future state (To-Be) model is designed. This model incorporates improvements and changes that align with the business strategy and goals.

4. Implementation Planning:

   • This involves planning how to transition from the current state to the future state. It includes defining projects, resources, timelines, and change management strategies.

5. Execution and Monitoring:

   • The final step is the execution of the plan and continuous monitoring to ensure that the changes are effective and to make adjustments as needed.

Tools and Techniques:

• IEM often employs a variety of tools and techniques for modeling and analysis. This can include process mapping tools, enterprise architecture software, data modeling tools, and simulation software.

Alignment with Other Frameworks:

• While IEM can be a standalone methodology, it often benefits from alignment with broader enterprise architecture frameworks such as TOGAF (The Open Group Architecture Framework), Zachman Framework, or FEAF (Federal Enterprise Architecture Framework). These frameworks can provide additional structure and guidelines to support the IEM process.

In summary, Integrated Enterprise Modeling as a methodology provides a structured approach for analyzing and improving an enterprise's operations across multiple layers. By combining IEM with a reference architecture and aligning it with established enterprise architecture frameworks, organizations can gain a holistic view of their operations and identify opportunities for optimization and integration.
